IMPROVEMENT lN SHOVEL-PLOWS.

Specication forming part of Letters Patent No. 96.010, dated October 19,1869.

'o LZ-Z whom, it 77am/ concern:

Be it known that I, E. A. KAMERER, of Greentown, in the county of Starkand State of Ohio, have invented certain new and useful Improvements inShovel-Blows; and I do hereby declare that the following is a full,clear, and exact description of my invention, reference being had to theaccompanying drawings, forming a part of this specification, and to theletters of reference marked thereon, of which drawings- Figure l is aplan of' my improved plow. Fig. 2 is a side elevation, and Fig. 3 is afront elevation, of the same.

My invention consists in so constructing a shovel-plow with threeshovels, one of which is fixed and the others movable, as thatthemovable shovels may be turned at any desired angle with the plow-beam,and set at any required distance from saidbeam, and, also, so that saidmovable shovels may be moved backward and forward with respect to thefixed shovel, so as to bring the three shovels nearly into line7 witheach other, and thus cause t-hem, when brought closely together, to actin a manner similar to a single-shovel plow, which is often verydesirable in cultivation between rows of plants.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the annexed drawings, A represents the plow -beam, to which aresecured the fixed sh ovel-standard D and the handles B B, which areunited at their upper ends by the cross-bar C, which is fixed in thestandard D, as shown.

The side beams,FF,have the irons S S bolted to their front ends, asshown, and the bolt E, which is passed through one of the holes, d, inthe plow-beam A, passes through holes in the ends of the irons S S,which are thus pivoted to the plow-beam, where theyr are held by the nuton the lower end of the bolt E, as shown.

The irons I I are bolted to the rear ends of' the beams F F, and havethe arms H H pivoted to them by the pins K K, as shown. These arms H Hare fixed in the side shovel-standards, G G, which have the shovels L Lbolted to them, and said standards are braced against the strain thrownon them in cultivating by the braces W W, which are bolted to the beamsF F, and have an eye at their lower ends, which are attached to thestandards G G by the staples ff, as shown.

The regulating-arms M M are bolted, .by flanges at their ends, to thestandards G G, and have the braces T T running down from them to saidstandards, as shown in Fig. 3. The holes b b are formed in these arms MM, which lie up under the plow-beam A, to which they are secured by abolt, P, which passes through a hole, b, in each of these arms M, upthrough the longitudinal slot a in the plowbeam A, where it is securedby the thumbnut R.'

The shovel N is bolted to the fixed standard D, as shown, and the braceU is inserted between the plow-beam A and standard D, to strengthen saidstandard against the strain thrown on it in cultivating.

From the foregoing description of the construction of my shovel-plow itis readily seen that by loosening the thumb-nut R the bolt l? may bemoved up or down the longitudinal slot a, which will cause acorresponding movement of the arms M M, and hence will turn thestandards G G around the hinge-pins K K, (the staples f f allowing thischange of position between the standards and braces WV W,) and thus willturn the shovels L L to any required angle with the beam A, where theycan be secured by simply tightening the thumb-nut R. It is furtherevident that by changing the bolt P from one hole b to another thedistance of the shovels L L from the plow-beam Avor from each other canbe varied as desired. It is also readily seen that by loosening thethumb-nut R and taking out the bolt E the shovels L L may be moved backtoward the shovel N, or, what is the same thing, the'plow-beam A,withits standard D, may be pushed forward, so as to bring the shovel Nnearly into line with the shovels L L, and that they can be secured inthis position by inserting the bolt E through a proper hole, el, in theplow-beam A. Aside from the advantages in cultivation resulting from thefacility with which the three shovels can be brought into line with eachother, this movement allows the operator to adjust the relativepositions of the shovels so as to conform to the different lines ofdraft caused by the varying height of the team, and to better adapt theposition of the handles, with respect to the shovels, to therequirements of the operator in manipulating the machine.

By removing the center shovel, N, a doublel shovel plow is attainedwithout additional 2 eamo Y expense, and with but little more Weightthan the ordinary double-shovel plow.

Having thus fully deseribed my invention, what I claim therein as new,and desire to secure by Letters Patent, is-

1. A shovel-plow provided with one fixed and tivo movable shovels, whenso constructed as that the movable shovels may be readily turned so asto assume any required angle with the plow-beam, and may be set at anydesired distance from said beam, and also so that said movable shovelsmay be readily moved into or nearly into line With said iixed shovel,substantially as is herein set forth.

2. The arm M, rigidly attached to the shovel standard G, and held by abolt, l?, Working in a slot, a, in the plow-beam A, when said arm servesboth to hold the shovel-standard G at the required distance from theplow-beam A, and also to regulate the angular position of said standardwith respect to said plow-beam," substantially as is herein speeied.

3. Pivoting the standards G of the side shovels, L, of a shovel-plow tothe side beams, F, by means of a hinge-pivot joint, II I K, and braceWV, having a loose joint, f, with the standard G, substantially as isherein speoied.

As evidence that I claim the foregoing I have hereunto set my hand, inthe presence of two Witnesses, this 14th day of July, 1869.

E. A. KAMERER.
